Summary figures for each species

The top row of bars shows all ITS2 sequence variants, while the bottom row of bars shows the associated ITS2 profiles. Legend refers to profiles only, not variants.

Colpophyllia natans

C. natans colonies at Cabritte Horn and East Tektite were dominated by a few different Breviolum profiles, with low levels of Cladocopium and Durusdinium that fluctuated randomly over time. At White Point, one colony was dominated by Cladocopium and one by Durusdinium.

Diploria labyrinithiformis

One colony at East Tektite (57) was dominated by Cladocopium, but otherwise D. labyrinthiformis was dominated by several distinct Breviolum profiles. These mostly remained the same over time within colonies, but changed for a few (colony 36, 37, 62). Will have to dig into these to see if these may be real changes or analytical artifacts.

Montastraea cavernosa

M. cavernosa is dominated by a couple of different Cladocopium profiles with some background Breviolum. Two colonies at White Point have a distinct Cladocopium profile, but there doesn’t appear to be any particular change over time.

Orbicella spp.

Orbicella colonies are sometimes dominated by Symbiodinium, Breviolum, and Cladocopium. Most stay the same over time, but some colonies (24 and 64, both at White Point), have mixtures of Symbiodinium and Cladocopium in 2017, and then only Cladocopium in 2019. Another colony at White Point (17) appears to change between two Cladocopium profiles. At other sites, little evidence of change over time.

Pseudodiploria strigosa

P. strigosa colonies contain mostly Breviolum profiles, with some evidences for changes among Breviolum types over time. Two colonies at East Tektite (45 and 54) are dominated by Cladocopium.

Siderastrea siderea

S. siderea hosts mainly Cladocopium profiles that do not change over time. A couple of colonies (7 and 73) may have fluctuating levels of multiple Cladocopium types. One colony at Cabritte Horn (51) is dominated by Breviolum.
